# Changelog
- 0.2.2 (2025-02-16)
* Exports the secp256k1 "point at infinity" as _CURVE_ZERO.
- 0.2.1 (2024-12-18)
* Adds 'serialize_point' for compressed-format serialization of
secp256k1 points.
- 0.2.0 (2024-11-08)
* Adds wNAF ("w-ary non-adjacent form") scalar multiplication, as
well as fast 'sign' and 'verify' variants for Schnorr and ECDSA
(disambiguated by a trailing apostrophe) that make use of it.
Each wNAF-powered function requires a 'Context' consisting of
precomputed secp256k1 generator multiples; one can be gotten via
'precompute'.
Note that the non-wNAF-powered sign and verify functions have
incurred a slight performance decrease (on the order of tens to
hundreds of microseconds) as a result.
* Adds 'parse_sig' for parsing compact signatures.
* Adds a dependency on the 'primitive' library (already transitively required
via 'ppad-hmac-drbg').
- 0.1.0 (2024-10-19)
* Initial release, supporting public key derivation and Schnorr &
ECDSA signatures on secp256k1.
